to a patient in any position, not merely when he is lying on his back,but also when he is lyin on a, side or lying face down.

A further object of this invention is to provide an anesthetic maskwhich makes it possible to place the patient in the best possibleposition for the operation to be performed and to continuing shown at l5for the mask M in Fig. 5'. Also, the wires l5 could be made continuousinstead of terminating in the plate l8, as shown.

In operation, having been anesthetized to a plane of anesthesia whereinhe can tolerate an intra-tracheal tube of suitable size, the patient isplaced on the operating table 24 in a, suitable position for theoperation to be performed, here ously administer the ether or anestheticin that Fig. 4 is a perspective view of the mask cage,

and

Fig. 5 is a perspective view of a slightly modified form of mask cage.

There is shown at I!) the anesthetic or ether mask of this inventionused in connection with an intra-tracheal tube II which is inserted intothe trachea of the patient F2. The mask In consists of a mask cage 14,entirely of metal or other suitable material, consisting of a pluralityof spaced-apart wires I5 extending from a flange [6 on a tube ILthewires l5 being joined together in a plate I8. To facilitate cleaning andto prevent corrosion, the cage M, if of metal, will preferably beprovided with a non-corrosive plating such as chromium plating or othersuitable material which is not affected by the ether or other anestheticthat may be used. A nipple having a knurled flange 2| is provided forconnecting the cage tube I! to the intra-tracheal tube H, theintra-tracheal tube ll being of a suitable semi-flexible material suchas rubber or plastic which will not react with either the anesthetic orthe body liquids to which it may be exposed.

A gauze bag 22, made of layers of gauze, is tied around the cage I4,being held by cords 23 if necessary, thus completing the mask, the wiresl5 being bowed, as shown, to provide a suitable cubical space within themask l4.

Obviously, the wires [5 maybe shaped somewhat differently than shown, amodified form beshown as being face down, in connection with anoperation to be performed on the back area of the patient. In suchposition the patients chin will be supported in a suitable supportingchin rest 25. The tube I I is inserted into the patients trachea, beingtaped to the face if necessary. The mask l4 having been joined to thetube H by means of the nipple 20, and with the gauze 22 in positionthereon, the anesthetist administen; the ether or other anesthetic bythe conventional drip method; that is, he merely drips it on to thegauze bag 22 at a suitable rate and the patients breathing will causesuction on the bag to deliver air and anesthetic vapor through the tube.

Other modifications and changes in the number and arrangement of theparts may be made by those skilled in the art without departing from thenature of this invention, within the scope of what is hereinafterclaimed.

The invention herein describedsand claimed may be manufactured and usedby or for the Government of the United States of America forgovernmental purposes without the payment of any royalties thereon ortherefor.
